IPC: B62D1/10
Filed: 1987-02-09
Abstract: PURPOSE:To remove looseness in meshing and prevent the rocking of a pad while make a timing belt slip to enable the rotation of a steering wheel when a third gear is unable to rotate, by energizing said timing belt which is meshed with the gear of a pad member by means of an energizing member. CONSTITUTION:The gear of a pad member 24 is meshed with a timing belt 36 which is meshed with the gear 21 of a fixed member and the rotation of the pad member 24 is stopped. And, when a steering wheel is rotated, a third gear 37 rolls on the timing belt 36 to interlock a steering shaft. Then, by energizing the timing belt 36 with a leaf spring 38, the looseness between the timing belt 36 and the gear 24 is removed, thereby, preventing the rocking of the steering pad. Further, when the rotation of the third gear 37 becomes hard due to dust, etc., by hardly moving the steering wheel, the leaf spring 38 is bent against its elasticity losing the tensile force with respect to the timing belt 36 and allows the third gear 37 to slip, enabling the rotation of the steering wheel.

IPC: B60W10/18
Filed: 1991-02-20
Abstract: PURPOSE:To provide a movement characteristic correcting device for a vehicle which performs control equal to that by a skillful driver without impeding an intension of a driver. CONSTITUTION:In a vehicle, a steering angle, a brake oil pressure, and a throttle opening are detected and vehicle movement is detected by means of a six-degree of freedom movement sensor comprising six acceleration sensors and an integrating circuit. By using above information, future movement, being a norm, of a vehicle and future movement of a real vehicle are estimated by means of the prestored movement characteristics of a vehicle being a norm. When an eminent deviation therebetween is predicted, a steering angle, a brake oil pressure, and a throttle opening are controlled so that the deviation is reduced. When a vehicle exceeds a movement limit, such as a spin, a drift, and under steer, by effecting control equal to that by a skillful driver, the vehicle can be restored back to a value within the movement limit, and an effect to prevent the occurrence of a risk is produced.

Title: Mass flow controller
Inventor: NISHIMURA KAORU
IPC: G05D7/06
Filed: 1986-02-07
Abstract: PURPOSE:To allow few configuration components to set an accurate flow by providing a variable orifice which sets a flow and compensates pressure and constituting an electromechanical force transducer so that liquid force made by the flow will not directly act on said transducer. CONSTITUTION:A mass flow controller 100 has a fixed orifice 1 and the variable orifice 2 which is provided at the downstream of the orifice 1, sets a flow and compensates pressure. An upstream pressure chamber 4 and a downstream pressure chamber 5 are partitioned by a diaphragm 6. By a spring 7 the diaphragm 6 is energized in a direction where the opening area of the orifice 2 increases, and in a direction where the electromechanical force transducer 8 decreases the opening area of the orifice 2. Moreover a pressure P1 at the upper stream of the orifice 1 is led to the chamber 4, while a pressure P2 at the downstream of the orifice 1 is led to the chamber 5. Thus the liquid force due to the flow does not directly act on the transducer 8, whereby few configuration components can set a highly accurate flow.
